Despite Ryuji Takasu's gentle personality, his eyes make him look like an intimidating delinquent so he is utterly hopeless about his chances of getting a girlfriend anytime soon, and does not have many close friends either. After being greeted by his hungover mother in the morning, Ryuji goes to school and is happy to find that he gets to be in the same class as his best friend Yusaku Kitamura and crush Minori Kushieda. However, it is then that he unexpectedly knocks into "the school's most dangerous animal of the highest risk level", Taiga Aisaka, who just happens to also be in his class, and is a good friend of Minori.
